Background technology
One of gordian technique that radio RF recognition technology (RFID) develops as Internet of Things, obtained in recent years development fast, be widely used at present the checking of product, the field such as trace to the source, can have significantly improved making an inventory, put storehouse, go out warehouse-in efficiency and reducing loss by theft rate etc. goods.
The method that at present more general use RFID tests to goods be for each cargo unit (such as using one case or one bag of goods as a cargo unit etc.) enclose a RFID label, because this label has unique product electronic code (EPC code), so it can be used as unique authentication foundation of goods.The process of providing label for each cargo unit is the process of the information of the corresponding cargo unit of this label of typing, the later process of examining goods, use exactly rfid interrogator to read the subsidiary label of goods, if the EPC code value reading is with the comparison of the record of typing is rear identical in advance, the identity of these unit kinds of goods of susceptible of proof, and further by record, obtain more details.Because RFID adopts contactless read-write mode, and once can read the characteristics such as content of a plurality of labels simultaneously, coordinate corresponding application program, compare traditional cargo survey mode, adopt RFID technology can greatly improve the efficiency of the kinds of goods course of receiving.
Yet the kinds of goods check system of this kind based on RFID still has its limitation, in the situation that some are special (particularly at valuables transport field), need to verify the order of putting of goods object, if only adopting above-mentioned mode examines goods, because read write line is disposable, read the content of all labels in its identification range, and receiving course is unordered, cannot verify whether putting of goods object sequentially had change.If read one by one cargo unit and verify that one by one whether its position is correct and adopt, such method often reads the unit of examining goods will carry out checkout procedure one time, and inefficiency is large to the expense of verification system, seem clumsy and don't economical.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of Product transport management method based on wireless radio-frequency and hash algorithm, by hash algorithm, identify fast the order of transporting cargo.
The technical scheme that the present invention takes is:
A Product transport management method based on wireless radio-frequency and hash algorithm, is characterized in that, comprises the steps:

(a) read successively EPC code the merging of the RFID label of goods subelement, by hash function, the EPC code merging is generated to Hash codes, and deposit the Hash codes of generation in long-range cargo survey center;
(b) Hash codes that the Hash codes that long-range cargo survey center generates (3) step and (a) step generate is verified, if the verification passes, enters transportation management process and finishes, if checking is not passed through, enters enquiry procedure.
Further, the read-write of described RFID label realizes by hand held mobile terminals, and described hand held mobile terminals carries out data communication by GPRS and described long-range cargo survey center.
The invention has the beneficial effects as follows:
(1) owing to having adopted hash algorithm, according to the characteristic of hash algorithm, the generation of Hash codes is unidirectional irreversible, be that identical input must produce identical Hash codes, can guarantee the checking of data, but cannot accurately calculate definite input value by Hash codes itself, even if this has just made to obtain Hash codes, also cannot instead release the order of each RFID label, the order that cannot reappear counterfeit goods, has guaranteed the security of proof procedure;
(2) Hash codes prestoring is kept at long-range cargo survey center, in the hand held mobile terminals of each use of examining goods, only there is hash function, and do not preserve the Hash code value that prestores for comparison result, all contrast verification processes are carried out long-range, and Hash codes result of calculation and Receipt Validation result are only uploaded in handheld terminal this locality.Adopt such separate mode, none knows original Hash codes field staff, thereby has stopped in the on-the-spot Hash codes of forging of examining goods to pass through the possibility of checking;
(3) hash function can make the data compression of random length be mapped as the data segment of a certain regular length, order proof procedure for each group only needs to upload this data segment (being Hash codes), without the EPC code to each RFID label, verify one by one, reduced like this data volume load of uploading, not only improve verification efficiency, also reduced taking and use cost wireless network resource;
(4) method that the present invention proposes is without special equipment, only need to increase tagged quantity and develop supporting software and can realize, owing to generally using hand held mobile terminals to carry out various forms of making an inventory to goods in freight industry at present, and there is the remote supervisory center of oneself in a lot of enterprises, therefore the present invention can realize to existing freight transportation inventory management system integratedly, and its cost is quite cheap;
